Seasonal Precipitation

This page will soon show and describe plots of the seasonal precipitation at our stations.

For the moment we are showing monthly total rain in a polar plot with the
months arranged clockwise around a circle. The seasonality of the rain fall on
Vancouver Island becomes very evident when it is displayed in this way.
The largest monthly fraction is written in the bottom left corner.
The number of daily totals (observations) is written in the bottom right.
The concentric circles, marked with grey numbers, show the fraction of the
annual rainfall in percent that each month represents.

In the example from Torquay Elementary School, shown below, you can
see that almost all (about 65 %) of the rain occurs in the months
of October through January. This is Victoria's rainy season.

Thanks to Natasha Ridenour for developing the software to generate
these plots.
